Product details
Overview
74AUP1G74DC-Q100 from Nexperia is a single-channel, positive-edge-triggered D-type flip-flop with asynchronous set (SD) and reset (RD) inputs, complementary Q and Q̅ outputs, and Schmitt-trigger inputs. It operates across 0.8 V to 3.6 V supply voltage, delivers ≤1.4 μA max ICC at +125 °C, supports up to 510 MHz fmax at 3.3 V, and is qualified to AEC-Q100 Grade 1 for automotive body control modules and ADAS sensor interfaces.
For engineers reviewing the 74AUP1G74DC-Q100 datasheet, 74AUP1G74DC-Q100 pinout, 74AUP1G74DC-Q100 application, or 74AUP1G74DC-Q100 equivalent, key selection criteria include its ultra-low static power consumption, IOFF-enabled partial power-down capability, wide VCC range compatibility, and guaranteed timing performance over –40 °C to +125 °C.
Technical Context
This device implements a master-slave D flip-flop architecture with fully asynchronous active-low set and reset controls that override clocked data storage. Its Schmitt-trigger inputs tolerate slow-rising signals and improve noise immunity without external conditioning.
The IOFF circuit disables outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for domain-isolated automotive subsystems. All DC and AC specifications are validated across three temperature grades: –40 °C to +125 °C (full automotive), –40 °C to +85 °C, and 25 °C typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 0.8 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Max ICC (Tamb = +125 °C) | 1.4 μA - ensures negligible quiescent current in always-on vehicle modules like door ECU wake-up circuits. |
| fmax (VCC = 3.3 V) | 510 MHz - supports high-speed sampling in camera serializer clock recovery and LIN bus timing generators. |
| tPD (CP to Q, CL = 5 pF, VCC = 3.3 V) | 3.7 ns - guarantees sub-4 ns propagation delay for real-time edge detection in motor position feedback paths. |
| IOFF Leakage (VCC = 0 V) | ±0.75 μA - prevents cross-talk and latch-up when adjacent rails power up/down asynchronously in multi-voltage ECUs. |
| ESD Rating (HBM) | 5000 V - meets automotive board-level robustness requirements per ISO 10605 without added protection components. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and infotainment applications. |
Pinout & Package
VSSOP8 package (SOT765-1), 2.3 mm body width, 0.5 mm pitch, 8-pin surface-mount plastic shrink small outline package optimized for high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CP | Clock input | Positive-edge-triggered master latch control; Schmitt-triggered for jitter tolerance on noisy harness-sourced clocks. |
| 2 - D | Data input | Stores logic state on CP rising edge; setup/hold times as low as 0.1 ns at 3.3 V enable tight timing closure. |
| 3 - Q | True output | Active-HIGH registered output; drives downstream logic or analog comparators with rail-to-rail swing. |
| 4 - GND | Ground reference | Primary return path for all internal currents; must be low-inductance connection to avoid ground bounce. |
| 5 - Q̅ | Complement output | Inverted copy of Q; eliminates need for external inverters in differential signaling or toggle configurations. |
| 6 - RD | Asynchronous reset | Active-LOW; forces Q = LOW / Q̅ = HIGH independent of CP - used for system initialization or fault recovery. |
| 7 - SD | Asynchronous set | Active-LOW; forces Q = HIGH / Q̅ = LOW regardless of clock - enables fast state preloading in safety-critical sequences. |
| 8 - VCC | Supply voltage | Core power rail; IOFF circuitry activates automatically when VCC drops below ~0.2 V to isolate outputs. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from –40 °C to +125 °C in engine control, transmission, and ADAS modules. |
| IOFF partial power-down mode | Outputs enter high-impedance state when VCC = 0 V, preventing backfeed into powered domains during sleep/wake transitions. |
| Schmitt-trigger inputs | Input hysteresis >150 mV at 3.3 V suppresses noise-induced glitches on long PCB traces or connector-linked signals. |
| Overvoltage-tolerant inputs | Accepts up to 3.6 V input signals even when VCC = 0.8 V - simplifies mixed-voltage signal routing in gateway ECUs. |
| Ultra-low dynamic power | CPD = 3.9 pF at 3.3 V minimizes switching power in high-frequency clock distribution networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G74DCKR | Non-automotive grade; rated –40 °C to +125 °C but not AEC-Q100 qualified; higher ICC (10 μA typ) at 3.3 V. | Lacks IOFF and fails AEC-Q100 stress tests; suitable only for non-safety-critical consumer-grade infotainment peripherals. | Select only if cost sensitivity outweighs automotive qualification and ultra-low-power requirements. |
| 74LVC1G74GW,125 | Same package (SC-70), but no IOFF; max fmax = 400 MHz at 3.3 V; lacks overvoltage-tolerant inputs. | Cannot interface safely with 3.6 V signals when VCC = 1.8 V; unsuitable for mixed-voltage gateways or radar front-ends. | Prefer only for legacy designs where IOFF and overvoltage tolerance are not required. |
Compared with SN74LVC1G74DCKR and 74LVC1G74GW,125, the 74AUP1G74DC-Q100 uniquely combines AEC-Q100 Grade 1 qualification, IOFF, overvoltage-tolerant inputs, and <1.5 μA ICC - making it the sole choice for safety-compliant, multi-rail automotive timing nodes.

FAQ
What is the minimum supply voltage for guaranteed operation?
The 74AUP1G74DC-Q100 is fully specified down to 0.8 V VCC, with functional timing and logic thresholds maintained across the full –40 °C to +125 °C range. At 0.8 V, fmax is 50 MHz and tPD is 53 ns (CL = 5 pF), enabling use in ultra-low-voltage subsystems such as battery-backed memory retention circuits.
Does this device support hot insertion or live swapping?
Yes - the IOFF circuit actively disables outputs when VCC drops below ~0.2 V, preventing back-current flow during hot-swap events. This feature is validated per JESD78 Class II latch-up testing (>100 mA), making it safe for modular ECU architectures with field-replaceable modules.
How does the Schmitt-trigger input improve system robustness?
Schmitt-trigger inputs provide ≥150 mV hysteresis at 3.3 V, rejecting noise spikes and slow-rising signals common on long harness runs or unshielded PCB traces. This eliminates metastability and false triggering without external RC filtering - critical for reliable switch debouncing and sensor signal conditioning.
Can SD and RD be used simultaneously without conflict?
No - per the function table, asserting both SD and RD LOW results in an invalid output state (Q = Q̅ = HIGH), which violates complementary output behavior. The device requires strict mutual exclusion: only one of SD or RD may be asserted at a time, or neither, to ensure deterministic Q/Q̅ behavior.
